Anaconda
Really, anacondas are unrealistically large snakes that can swallow a whole human being. Due to their mere size, Anacondas are still very dangerous despite their lack of venom. Actually, this snake likes to wrap victims around the midsection and then continues to compress them until they are completely crushed or totally suffocated. It begins to swallow you whole from that point on. Uh. GULP.
Desert Horned Viper
Cerastes cerastes is a venomous viper species, commonly known as the Saharan horned viper or the horned desert viper, native to the deserts of northern Africa and parts of the Arabian Peninsula and the Levant. The Desert Horned Viper is moving sideways, which is absolutely scary! It is usually found in the the Middle East and northern African regions. Oh, and they’re unbelievably toxic, too… so you know, stay far away, far away.
